What is it?
It's an RPG design challenge where you complete each other's games.

How does it work?
It has three stages, which are entirely anonymous.

In the first stage you submit a 700-1100 word RPG by midnight on Tuesday, August 11th, 2015. Maybe it's playable, but likely it's not. What you're trying to do with your 700-1100 word submission is give the next designer a core they can take forward.

In the second stage I randomly reassign the submissions back to everyone, and you have roughly twelve days to increase them by 1000-1200 words. You can change or delete whatever you want, as long as you keep what you believe are the important conceits of the game, and end up with an increased wordcount in the target range. These are due by midnight Sunday, August 23.

Then in the third stage I randomly reassign the stage two games, again making sure no one gets one they submitted in stage one or worked on in stage two, and you work the one you get up by an additional 2000 words. You have another fifteen days for this stage. And like before you can keep, change, delete whatever you want. Your goal is a playable game in the target wordcount range. And they're due midnight Sunday, September 6.

DETAILS ON HOW THE CHALLENGE IS TRACKED IN RPGGEEK
Each entry in the challenge has the following information in RPGGeek...

An RPG entry for the game as a whole.

An RPG item entry for the submission.

A version of that RPG item for each stage of the submission: these are labeled "Stage One [FORMAT] Version", "Stage Two [FORMAT] Version", and "Stage Three Final [FORMAT] Version", where [FORMAT] is the file format of the file available on the #Threeforged webpage.

If a an earlier stage had an alternate title, that title will be in the description of the RPG Item, and will be an alternate name for the item.

Note on Designer Credits
Because of the nature of the challenge, the different versions of each game (Stage One, Two and Three) can be radically different from each other in terms of theme, mechanics, and overall style. Designers of the earlier stages of a game may not recognize, or even like, the later stages, and little of the Stage One game may be present in the Stage Three version. Each entry is treated as a single game credited to all three designers in the RPGGeek database, but each stage version should also be considered an independent creation of its designer as well.
